rosdep tutorial#

rosdep is a command-line tool for installing system dependencies rosdep is ROS’s dependency management utility that can work with ROS packages and external libraries.

usage#

first use#

sudo rosdep init
rosdep update

rosdep init create folder rosdep under /etc/ros
rosdep update download index files to local cache

index file url set /etc/ros/rosdep/sources.list.d folder

for example python packages from pip defined at https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml

index file for ros distro download from distro location that config https://raw.githubusercontent.com/ros/rosdistro/master/index-v4.yaml

run#

update

run rosdep update to update cache index

rosdep will check for package.xml files in its path or for a specific package and find the rosdep keys stored within

rosdep install --simulate --from-paths ~/workspaces/project/src --ignore-src
  • –form-path: specifies the path to check for package.xml files to resolve keys for
  • y: means to default yes to all prompts from the package manager to install without prompts
  • –ignore-src: means to ignore installing dependencies, even if a rosdep key exists, if the package itself is also in the workspace

demo#

install python package using rosdep

  • add package name to package.xml depend tag
    1. check python.yaml for package correct name
  • run rosdep install
package.xml
<depend>pynput-pip</depend>
terminal
rosdep install --from-paths ~/ros2_ws/src/camera_calibration_gazebo --ignore-src

check python package naming

browse to https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml

pynput-pip:
    debian:
        pip:
        packages: [pynput]
    ubuntu:
        pip:
        packages: [pynput]

resolve#

resolve to system dependencies

install from pip
rosdep resolve pynput-pip
#pip
pynput
install from apt
rosdep resolve python-opencv
#apt
python-opencv
